- The cheapest shipping service is First-Class Package Service, a domestic mail service offered by USPS. It is designed for mailing lightweight packages that weigh up to 15.99 ounces and offers delivery in 1-5 business days. It includes features such as USPS Tracking, which allows customers to track their packages and receive delivery confirmation. USPS prices start at $4.75, but we don't have any control over shipping prices.
- Many customers ask if they can ship their products in an envelope. Unfortunately, we cannot ship merchandise in a paper envelope because it requires extra protection, and USPS does not provide a tracking number for this type of service.
